Update contentScript.js

[FarihaAli]

No messages are displayed if there are dangling RETRY msgs from the past with no LogStart or LogEnd ie null e.g Dangling msg as below: It stops all the messages from being displayed

Earlier a change was suggested and RETRY msgs were discarded but that impacted other tenants, to have no impact the code now uses LogStart gt datetime'1900-01-01T01:02:50' which is from long past and will remove RETRY msgs with LogStart as null

Thank you for the explanation and the fix! Now it's clear what the previous changer of this function was trying to achieve.
